Here we cover how to upgrade to latest Longhorn from all previous releases.

Upgrading Longhorn

There are normally two steps in the upgrade process: first upgrade Longhorn manager to the latest version, then manually upgrade the Longhorn engine to the latest version using the latest Longhorn manager.

1. Upgrade Longhorn manager

2. Manually Upgrade Longhorn Engine

After Longhorn Manager is upgraded, Longhorn Engine also needs to be upgraded using the Longhorn UI.

3. Automatically Upgrade Longhorn Engine

Since Longhorn v1.1.1, we provide an option to help you automatically upgrade engines
